SCALE- DESTBOYING COMPOSITION.

a citizen of the United States, residing at Larchmont, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Scale- Des troying Composition, of which the following is a specification.

This invention relates to compositions for destroying'San Jose scale and similar scale, fungi and the like, and comprises the waste liquors from the manufacture of wood pulp by the sulfite process, in conjunction with kerosene, or. similar oily material.

-Waste cellulose sulfite liquor may be concentrated to a gravity of about 30 Baum, in which condition, a parently because the sulfonated products which are present in the compound, it exhibits peculiar emulsifying and solvent properties for certain oils, and in particular ordlnary kerosene oil. When properly mixed with kerosene oil, almost clear solutions are produced, in spite of the large percentage of water present, which should emulsify or separate from the oil and produce solutions of a'cloudy or turbid appearance. Under the conditions of preparation as hereinafter/ set forth in an illustrative way, turbid products need not be produced, but instead clear solutions," or solutions which are substantially clear, barring per? haps the existence of a sli ht scum ufpon the surface, may be prepare which have unusual virtues with respect to the destruction of scale in orchards, and for other kindred purposes.

r A suitable "composition illustrative of my invention ismade by heating the waste sulfite liquor, concentrated to a gravity of about 30 Baum, to a temperature of. 80 (3., or over, and in emulsifying or incorporating therewith kerosene oil. having a flash point from 100 to 150 Fhr. Ordinarily two parts of kerosene may be combined with one part of the concentrated waste sulfite liquor. The two components are beaten together in a suitable emulsifier; the sulfite liquor being first placed in the mixin apparatus and the kerosene gradually adde thereto. It is desirable toadd the kerosene slowly in order to start the combination with the sulfite liquor to the desired extent in or.

der that clear or substantially clear products may be obtained. It is difiicult to say just Specification of Letters Patent. Application filed January 14, 1908. Serial No. 410,834.

Patented Aug. 18, 1908.

what is the action of the concentrated sulfite liquor upon the kerosene oil. The sulfite liquor contains sulfonated products, probably a sulfonic compound of lignin in combination with lime, and these may have some obscure action upon the kerosene oil, Whereby it is brought into. a state of solution, or seeming solution. While I prefer to use the waste sulfite liquor of about the concentration above specified, I may, of course, use lesser strengths, in which case it is generally desirable to reduce the proportion of kerosene employed. Various other petroleum products of a heavier consistency, or even certain of the crudeproducts may be used. Tarry matter is as a rule disadvantageous. In using my composition, it is generally diluted with from ten to twenty times its volume of water, and applied to the trees, etc.,

by means of a suitable spraying device. Ten parts of water to one part of the composltion is the proportion which I prefer to use, except dilution with the times or more of its volume.

ofwater, that a true emulsion is produced with the particlesof kerosene oil in the state of the finest possible subdivision, so that very permanent and satisfactory spraying H11X-' tures are made; permitting of a thorough application of the composition without trouble from clogging of the spraying-apparatus.

Inasmuch as the waste liquor may be readily neutralized by the addition of lime or other alkali during the operation of concentration, it is possible to make an entirely neutral oil and sulfur scale destroying composition} a composition, which to my knowledge, has heretofore not been employed by orchardists. I q It is evident in the use of whale oil soap and other kinds of soap to effect emulsificatiqn with kerosene oil that an alkaline reaction is given to the composition through thepresence of free alka'li in the soap, or by the hyline reaction has drawbacks because of occasional evil eflects upon trees. This is especially noticeable if the composition is .washed intothe ground so as tojcome in contact with the roots of the trees. My composition, therefore, which may be made of an entirely neutral character, is particularly adapted for use on trees of a sensitive character. It further has the great advantage of employing a high efficient sulfur-carrying adhesive and scalecidal body, the sulfite liquor; in conjunc- A I bodies than those mentioned may also be introduced into my composition, such as flowers of sulfur, calcium sulfid, sodium'cresylate and similar material having an inhibiting action on scale growth. I

What I claim is 1. A composition of matter {or the destruction of scale, which comprises kerosene oil and concentrated waste cellulose sulfite liquor.

2. A composition of matter foir destroying scale, which comprises an emulsion of Waste sulfite liquor of about Bauin with kerosene oil.

3. A composition of matterfor destroyin scale, comprisin an emulsion of kerosene o and waste cellu ose sulfite liquor in a con centrated condition; the proportion of the keroseneoil being in excess of the waste cellulose sulfite liquor.

4. A scale destroying compound consisting substantially of kerosene and waste cellulose sulfite liquor.

5. A scale destroying composition comprising a petroleum oil, and substantially neutral waste cellulose sulfite liquor in a concentrated condition.

6. A scale destroying composition consisting of approximately two parts of kerosene oil and approximately one part of neutral waste cellulose sulfite liquor of a gravity ofapproximately 30 Baum.

In testimony whereof- I have aflixed my signature in presence of two witnesses.
